Inside Line is reporting today that the Model S Signature Performance, the top-of-the-line trim level, is already sold out and Tesla Motors is no longer accepting pre-orders. Customers now wanting to purchase the Model S Signature Performance will have to be put on a waiting list.

The Signature Performance ups the ante with an 85 kWh lithium-ion battery pack (8-year, unlimited miles warranty). As its name implies, performance improves greatly with 0-60 times dropping to 4.4 seconds while the top speed increases to 130 mph. The maximum driving range of the Signature Performance is listed at 300 miles.

The first deliveries of the Model S Signature Performance will begin on June 22. Those who have ponied up for the standard Model S will receive their vehicles later this fall. Those who haven't already pre-ordered the standard Model S still have time to get in line; Tesla is still accepting $5,000 deposits for the vehicle.

It's painfully obvious why the majority of people (regardless of their political view) are uneasy with the oil situation (not agreeing that they want anyone to be punished).

A world utterly dependant on a commodity which is in very short supply and which many believe could lead to global wars in the near future unless said dependence is removed.

A push towards renewable and therefore sustainable energies is the logical solution, and it's also logical that to accelerate this process the government adds an incentive to the population to invest in this new technology.

It has nothing to do with political stance in general - it's simply about sustainability and national security, which pretty much all parties would agree are important.

Except that even switching to EVs won't cure those ills, only shift them to others. Think about it, once we are off "foreign oil", these EVs make us dependent on those who will supply the needed metals for producing the motors and batteries. So after we avoid a war for oil, then we have a war for Lithium, or one of the "rare earth" metals. Instead of having wars in the middle east, we now focus on China and South America. What happens to stability in the Middle East once the oil cash cow dies? Will the Saudi's begin to rattle their swords demanding cheaper supplies of Lithium? It sounds silly, but you have to think about it.
